The boxplot glyph draws the boxplot for each of the areas being presented in the group/row. This can be up to 5 areas (boxplots) at a time. The color scheme of each boxplot matches the color assigned to the area being presented in this graphic row. Each boxplot is redrawn from the attribute data provided in the boxplot data.frame passed to the glyph code via the panelDesc panelData variable by name. The boxplot data.frame is the output of the standard R boxplot function when plot= parameter is set FALSE. This produces a data.frame of the information needed to draw the boxplots and outliers. The name of the data.frame is passed to the boxplot glyph via the panelData vector in the panelDesc data.frame used to describe the requested linked micromap.

The boxplot data.frame created by calling R's boxplot function with plot=FALSE contain a row of boxplot attributes for each set of data passed to it originally. In this case it would be the data for each area to be analyzed by micromapST. The data.frame is passed by name using the panelData row in the panelDesc data.frame.
For the boxplot glyph, doesnot use the col1, col2, col3, refval or reftxt rows of the panelDesc data.frame.
The following is an example of a section of a boxplot glyph column in a linked micromap:
The statsDFrame and panelDesc data.frames reside in the global environment and automatically accessible to the process along with several other major structures.
